I haven't read the book, but found the paragraph fun to read. The last statement bears thought, and interestingly rings true. Looks like I have missed out, and may yet read the book.
It’s a free kindle download. I’m 3/4 through it.
One chapter that lingered with me is Chapter 58 Brit. It’s short as many of the chapters are, and muses on the analogy of land and sea, with the conclusion:
Consider all this; and then turn to this green, gentle, and most docile earth; consider them both, the sea and the land; and do you not find a strange analogy to something in yourself? For as this appalling ocean surrounds the verdant land, so in the soul of man there lies one insular Tahiti, full of peace and joy, but encompassed by all the horrors of the half known life. God keep thee! Push not off from that isle, thou canst never return!
